Technical Introduction: "Carburizing and Nitriding Heat Treatment"

Technical Introduction: "Carburizing and Nitriding Heat Treatment"

We have a wealth of accumulated technology in the field of processing techniques for reducing material costs, which is one of our strengths.

Carburizing and nitriding treatment refers to the process of simultaneously or continuously performing carburizing and nitriding. Generally, for materials with poor hardenability, such as low-carbon low-alloy steel, carburizing is conducted while adding ammonia gas or similar substances to achieve both carburizing and nitriding, aiming to improve the hardenability of the material at lower transformation temperatures. By performing nitriding, it becomes possible to effectively introduce hardness into materials that do not harden with carburizing alone. The quality characteristics obtained from carburizing and nitriding treatment include improved wear resistance and fatigue strength, similar to carburizing, as well as enhanced softening resistance. Recently, carburizing and nitriding treatment has also been applied to alloy steel or bearing steel for the purpose of improving mechanical properties. ● For more details, please contact us.

Technical Introduction: "High-Frequency Heat Treatment"

Technical Introduction: "High-Frequency Heat Treatment"

Capable of handling everything from large products to precision parts!

High-frequency hardening is a process that can be described in one word as heating and cooling only the necessary parts to harden them. 【Principle】 1. Utilizing the phenomenon of electromagnetic induction Electromagnetic induction occurs when a coil A connected to a power source is placed near another coil B (both coils are in a non-contact state) and the power is turned on, generating a magnetic field. At this moment, a current is induced in coil B as well. (The same occurs when the power is cut off.) The phenomenon of current being induced in coil B is called electromagnetic induction. 2. Heating the product with the induced current By using the current (eddy current) induced by electromagnetic induction, placing the product (metal) instead of coil B allows current to flow through the product. When current flows through the product, Joule heat is generated due to resistance, and the product is efficiently heated through a direct heating method as it self-heats. 3. Heating only the necessary depth of the necessary parts By shaping coil A to match the shape of the part of the product that needs to be heated, only the necessary parts are heated. The higher the frequency of the power source, the more the induced current concentrates on the surface of the product (this is called the skin effect). The frequency is selected arbitrarily based on the product shape (size) and the desired depth of the hardened layer. ● For more details, please contact us.

Introduction to Heat Treatment: A Beginner's Guide from the Basics

Introduction to Heat Treatment: A Beginner's Guide from the Basics

[Functional and Property Improvement] Basic Knowledge of Heat Treatment Used in Automotive Parts and Aircraft Parts

Heat treatment refers to a metal processing technique aimed at improving the properties of metallic materials. The heat treatment process involves heating, holding, and cooling components or materials, which changes their characteristics. Why is heat treatment necessary? Metallic materials have the property of being brittle as they become harder. They are strong against deformation, but when a certain amount of force is applied, they can suddenly break or crack. It is common to apply heat treatment to improve the properties of metallic materials. We are currently offering a beginner's booklet that provides basic knowledge about heat treatment as a gift. *For more details, please refer to the PDF document or feel free to contact us.*

Technical Introduction: "Heat Treatment of Aluminum Alloys"

Technical Introduction: "Heat Treatment of Aluminum Alloys"

From large products to small items, we accommodate a variety of products!

Aluminum alloys are strengthened by heat treatment processes. Below are some representative treatments. 1. Solution Treatment and Natural Aging (T-4) This heat treatment involves rapidly cooling (water cooling) the aluminum alloy while maintaining a state where magnesium (Mg), copper (Cu), silicon (Si), and other elements are dissolved in the aluminum base (supersaturated solid solution). 2. Solution Treatment and Artificial Aging (T-6) This treatment improves hardness and mechanical strength by precipitating compounds of magnesium (Mg), copper (Cu), silicon (Si), etc., that were dissolved during the solution treatment, and is accelerated by raising the temperature to a certain level. 3. Stabilization Treatment (T-5) For some aluminum parts, to prevent changes in properties due to temperature rise during use, this process stabilizes the characteristics of the parts at a temperature slightly higher than the operating temperature. 4. Annealing Treatment (O Treatment) Annealing may be performed at around 350°C to improve workability. This is done when reprocessing parts that have already undergone T-6 treatment, particularly to reduce deformation in parts that are likely to deform. ● For more details, please contact us.

Austenitic stainless steel also becomes hard!

Austenitic stainless steel also becomes hard!

Improvement of wear resistance! Introducing nitriding in a blog format!

Surface heat treatment involves two methods: one is to heat elements that lead to hardening, such as carburizing and quenching, allowing them to permeate from the surface, and the other is to heat only the surface of materials that can be hardened, such as high-frequency quenching. This time, I will talk about nitriding. Nitriding is a heat treatment that creates iron nitride (FeN), a compound of nitrogen (N) and iron (Fe), on the surface of steel, making only the surface hard. There are two types: gas nitriding, which uses gas, and salt bath nitriding, which uses a salt bath furnace. *For more details, please refer to the related links on the blog. Feel free to contact us for more information.

[Metal Heat Treatment Guide] What is Carburizing?

[Metal Heat Treatment Guide] What is Carburizing?

It is possible to achieve both wear resistance and toughness! This is mainly applied to heavy machinery and machine parts.

"Carburizing" refers to a treatment in the processing of metals (especially low carbon steel) that involves adding carbon with the aim of hardening the surface layer. It is possible to harden only the surface of the metal while maintaining a flexible structure internally. Post-treatment after carburizing creates stress between the surface layer and the interior, which provides resistance to cracking. This process is mainly performed to improve wear resistance in heavy machinery and mechanical components. [What is Carburizing] - A treatment that adds carbon for the purpose of hardening the surface layer in the processing of metals (especially low carbon steel). - Mainly conducted to enhance wear resistance. - It is possible to achieve both wear resistance and toughness. *For more details, please refer to the PDF document or feel free to contact us.

Gas carburizing and carburizing nitriding

Gas carburizing and carburizing nitriding

Carbonitriding contributes to the improvement of strength characteristics of various machine steel parts, including automotive components!

We would like to introduce our heat treatment process of "gas carburizing and carburizing nitriding." "Gas carburizing" involves heating steel materials to approximately 900 to 940°C in an atmosphere of endothermic gas primarily composed of CO, N2, and H2, with the addition of enriching gases such as butane and propane, allowing carbon to penetrate the surface of the material. This is followed by quenching to harden the material. On the other hand, "carburizing nitriding" is a process where carbon and nitrogen are simultaneously penetrated into the surface of steel at a lower temperature of approximately 800 to 880°C compared to standard gas carburizing, followed by quenching to harden the material. 【Characteristics of Gas Carburizing】 ■ Applicable steel types: Low carbon alloy steels such as skin-hardening steels (SCM, SCr, SNCM, etc.) ■ Achieves a thick surface hardening layer while ensuring high toughness internally ■ Depth of hardening layer and surface hardness can be adjusted according to requirements ■ Several types of quenching oils can be selected based on internal hardness and component shape ■ The surface has a smooth finish with a light gray color (in the case of low-temperature tempering) ■ Improves wear resistance, impact strength, and fatigue strength *For more details, please download the PDF or feel free to contact us.
